c# - Is it possible to represent non gregorian dates as DateTime in .NET? -


i'm having trouble representing persian (solar hijri calendar) dates datetime in c#, on days of particular months, example 31/04 in gregorian calendar such date meaningless:

system.globalization.persiancalendar p = new system.globalization.persiancalendar(); datetime date = new datetime(2013,7,22); int year = p.getyear(date); int month = p.getmonth(date); int day = p.getdayofmonth(date); datetime d1 = new datetime(year, month, day);

the above code result in argumentoutofrangeexception saying: year, month, , day parameters describe un-representable datetime.

which expected.

how can represent persian dates datetimes in .net taking accounts dates such 30/02 , 31/04?

the above code result in argumentoutofrangeexception saying: year, month, , day parameters describe un-representable datetime.

yes, because unless specify calendar, datetime arguments expected gregorian. can specify calendar though:

datetime d1 = new datetime(year, month, day, p);

note if take d1.year, you'll 2013, not year... datetime always gregorian, basically. however, if use culture has persian calendar default calendar, convert values appropriately when format datetime string. edit: unfortunately, per documentation:

currently, persiancalendar class not optional calendar culture supported cultureinfo class , consequently cannot default calendar.

as comment has mentioned noda time, can address that: doesn't support persian calendar yet. supports lunar hijri calendar, not solar 1 :( adding future release...

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
